  • Patent number: 5511445
    Abstract: A disposable, and reusable, hand grip is constructed as a flexible multi-ply band adapted to be wound around the circumference of a handle on a tool or other device, so that the person can exert an effective grip action on the hand grip. The multi-ply band includes a core sheet formed of a resilient foam material, a first surface sheet of rubber on one major face of the core sheet, and a second surface sheet of a woven fabric material on the other major face of the core sheet. The thickness of the band is designed to effectively increase the cross sectional thickness of conventional handles, so that the person has a more comfortable, less cramped, grip on the handle (hand grip).
